A sandwich-type structural panel is formed by a core of insulating material having opposing skins or face surfaces bonded to opposing planar sides of the core and defining rectangular recesses at each end of the panel. The panel is further characterized by elongated rigid stiffeners extending coextensive with the thickness of the core material and its length between the encapsulating skins. The spacing of the stiffeners is such that a point load of a fixed amount centrally applied to either planar surface or longitudinal edge of the panel generates a load deflection ratio of 1:1 between the central portion of the panel and its respective edge, thus providing a balanced efficient panel.
